set protocols bgp neighbor soft-reconfiguration
The set protocols bgp neighbor soft-reconfiguration command enables you to generate inbound updates from a neighbor and change and activate BGP policies without clearing the BGP session. Changes in BGP policies require the BGP session to be cleared which can have a large negative impact on network operations.
The delete protocols bgp neighbor soft-reconfiguration command disables this setting.
Command Syntax
set protocols bgp [vrf <vrf-name>] {neighbor <ip>| peer-group <peer-group> |interface <interface>} {ipv4-unicast|ipv4-labeled-unicast|ipv6-unicast|ipv6-labeled-unicast} soft-reconfiguration inbound
delete protocols bgp [vrf <vrf-name>] {neighbor <ip>| peer-group <peer-group> |interface <interface>} {ipv4-unicast|ipv4-labeled-unicast|ipv6-unicast|ipv6-labeled-unicast} soft-reconfiguration inbound
Parameter
Parameter | Description |
vrf <vrf-name> | Optional. Specifies a VRF name. The value is a string. It’s a user-defined VRF set by the command set ip vrf <vrf-name> [description <string>]. |
{ipv4-unicast|ipv4-labeled-unicast|ipv6-unicast|ipv6-labeled-unicast} | Specifies the type of the address family. |
neighbor <ip> | Specifies the IPv4/IPv6 address of a peer. |
peer-group <peer-group> | Specifies a peer group. |
interface <interface> | Specifies an L3 interface for BGP connection. The value could be a VLAN interface name, loopback interface name, routed interface or sub-interface name. |
Usage Guidelines
- To perform inbound soft reconfiguration, the BGP speaker must store all received route updates, regardless of the current inbound policy.
- When inbound soft reconfiguration is enabled, the stored updates are processed by the new policy configuration to create new inbound updates.
Example
• This example enables to generate inbound updates from a neighbor and change and activate BGP policies without clearing the BGP session.
